Each of the cubes in each group is provided with a selected numeral on each of its six faces in a manner whereby the numerical sum on the faces of at least any pair of cubes adjacent another pair along a common line of symmetry is the same regardless of the various cube combinations.

EDUCATIONAL rov nsvics This application relates generally to educational toy devices and more particularly to a multiple-cube device wherein each face on each cube is provided with a selected numeral and wherein each of the cubes are so interconnected as to be combined into any number of cube configurations, the numerical total on the faces of at least any pair of said cubes adjacent each other along a common plane of symmetry being the same regardless of the various cube configurations.

Cube devices have always fascinated young children and, because of their multisided configuration, readily lend themselves for use as building blocks or as an educational device after a number of words, pictures, or numerals are placed on one or more of its faces. It is, therefore, an object to make use of a multiplicity of such cubes and to interconnect them in such a way and provide a numeral on each of the cube faces in such a manner so that the device may be used as both a toy and an educational device whereby the child's interest is maintained during simple arithmetic exercises.

Another object of the invention is to provide an educational cube device wherein a plurality of cubes are provided each being interconnected to one another by means of a double hinge and each being provided with a selected numeral on each of its six faces so that regardless of the many cube configurations which may be formed of the plurality of cubes the numerical total on the faces of at least any pair of the cubes adjacent to another pair along a common plane of symmetry is always the same regardless of the various cube configurations.

A further object of the present invention is to provide an educational toy device as described wherein the interconnected cubes are arranged to form a plurality of groups, the double hinges between groups permitting movement in one plane and the double hinges between cubes in each group permitting movement in another plane perpendicular to the one plane whereby a large variety of cube configurations is permissible.

A still further object of the instant invention is to provide an educational toy device as characterized wherein the double hinges between cube groups are located at alternate ends of adjacent groups for pivotal movement between groups in one plane perpendicular to the pivotal movement between cubes in each group in another plane.

A still further object of the present invention is to provide an educational toy device as characterized wherein four of such groups is provided each having four cubes and each cube face being provided with a numeral from 1 to 4 so that regardless of the various cube configurations the numerical total on the faces of at least any pair of the cubes adjacent another pair along a common plane of symmetry is always equal to 10.

A still further object of the instant invention is to provide an educational toy device as described wherein the plurality of cubes are capable of forming a 4X4Xl device wherein the numerical total on the faces of the cubes lying along each of the four diagonals of the device is also equal to 10.

Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings wherein:

FIG. 1 is a front perspective view of the educational toy device according to the present invention;

FIG. 2 is a rear perspective view of the device according to the present invention;

FIG. 3 is a front perspective view similar to FIG. 1 except that each of the cube roups is shown after being slightly pivoted away from one another;

FIGS. 4 and 5 are, respectively, perspective views showing two possible configurations of the cubes; and

FIGS. 6 and 7 are side views showing a typical double movement permitted by each of the double hinges between a pair of the cubes.

Turning now to the drawings wherein like reference characters refer to like in corresponding parts throughout the several views, there is shown in FIGS. 1 and 2 a front and back perspective view, respectively, of the educational toy device it) according to the present invention. As can be seen, a plurality of cubes If is provided each having a selected numeral on each of its six faces between I and 4 and each being interconnected by means of a double hinge 12 between each of the cubes located in each of the cube groups 13, M, 15 and 16. Each of the cube groups is also interconnected by means of a double hinge 17 at alternate ends of each pair of cube groups so that the tops of groups 13 and M and of groups and 116 are interconnected by means of the double hinge l7 and the bottoms of the groups 114 and 15 are also similarly interconnected. With reference to FIGS. 6 and 7, it is to be noted that each of the double hinges 112 between each of the cubes in each group is shown to be typically comprised of a first hinge strip 18 extending between the lower right edge of face 4 and the upper left side edge of face 1 on the adjacent block. A pair of second hinge strips 19 comprise the remainder of the double hinge l2 and extend between the lower left edge of the face 4 and the upper right edge of face I on the adjacent block. Of course, each of the first hinge strips lid is disposed between the pair of second hinge strips 19 which are spaced a suitable distance from each other as clearly seen in FIG. I, for example. Such an arrangement of first and second hinge strips is intended for each of the double hinges 112 between each of the cubes in each group so that it is to be understood that a similar arrangement of first and second hinge strips is intended for such cubes as is evident from FIGS. 1-5 of the drawings. Similarly, the double hinge 117 comprises a single third hinge strip 21 extending along the face two of the uppermost block in group 16, downwardly over its upper left side edge, and terminating on the right side face of its adjacent uppermost block in group 15. A pair of fourth hinge strips 22 of the double hinge 17 extend across the upper face: one of the uppermost block in group 15, downwardly over its upper left side edge, and terminating on the left side face of the uppermost block in group 16. Such a double hinge 17 is intended to be typical for each of the remaining double hinges between the tops of groups 13 and 14 and between the bottoms of groups 14 and 15. Double hinges l2 and 17 are generally of the type which have been heretofore devised in the game and toy art so that as such they form no part of this invention except for their use in combination as an educational toy device.

With reference to FIG. 3, it will be seen that the double hinges l2 permit each of the cubes in each of the groups 13 through 16 to pivot in the directions shown by the double arrows and, more specifically in FIGS. 6 and 7, as shown by the arrows between the adjacent blocks. Similarly, the double hinges l7 permit adjacent cube groups to pivot in a dual direction as shown by the double arrows. With the double hinges l2 and R7 so placed it can be seen that the educational toy device of the present invention is capable of being arranged so that its cubes form any number of combinations, two of such combinations being shown in each of the FIGS. 4 and 5.

The numerals for each of the six faces of each cube are so selected that the numerical total on any four cubes adjacent one another in a vertical or horizontal direction, or diagonally across the front and back of the device as shown in FIGS. 1 and 2 or as a rectangular cluster of four cubes, will always be equal to l0. It can be therefore seen that a common plane of symmetry exists for such groups of four cubes (with the exception of the diagonal groups) so that with any such common plane of symmetry for any pair of cubes adjacent another pair therealong the numerical total on each of the four such faces will be always equal to 10. With such an educational toy device, the child will be not only sufficiently occupied while attempting to achieve some desired configuration for the interconnected cubes but will at the same time be conducting an arithmetic exercise because he will have been told that with any four adjacent cubes along a vertical, horizontal, diagonal or in a rectangular cluster, he will be able to add up the numerals on such on the faces of these cubes and always come up with a total of IO. It has been found among children that many slow learners in arithmetic have greatly improved upon their learning ability with the use of such a device simply because of the challenge that the device presents in terms of the various configurations possible and the competition with other children in striving for new and different combinations while at the same time repeating their exercises in simple arithmetic in constantly adding up four numerals equal to 10.

Obviously many modifications and variations of the present invention are possible in the light of the above teachings. For example, different numerals for different numerical totals and more or fewer blocks and groups as that disclosed are possible without departing from the spirit of the invention. it is, therefore, to be understood that within the scope of the appended claims the invention may be practiced otherwise than as specifically described.
